This is a combination of 3 types of indicators :
1) Simple Moving Average
2) Exponential Moving Average
3) Bollinger Band
Idea is to plot any of the above indicator with a particular period length from a different timeframe to the timeframe on which you are currently working.
eg : As shown in the chart we have indicator plots from daily timeframe plotted/shown on the current 4hr time frame .
Similarly, you can have indicator plots from 4hr timeframe to be shown on any other timeframe and so on.
Basically you can select plots from any timeframe to work with on any other timeframe of your liking .
Not a rocket science, just play around with it and you will understand :)
